| Responsive email works on the same principles as RWD: |
|
 |
| Fluid Images |
| max-width:100% is your friend, just like on the web. |
|
 |
| Fluid Structure |
| You can use percentage-based tables, too. Don’t touch ems, though. |
|
|
|
 |
| Media Queries |
| They don’t work everwhere, but when they do… |
|
 |
| Bulletproof Buttons |
| Don’t use images for buttons. There’s a better way. |
